Crane Control Class 6815 Type A Lifting Magnet Controllers
TYPE A LIFTING MAGNET CONTROLLERS FOR 31 TO 130 AMPERE GENERATOR POWERED MAGNETS
Pricing and Ordering Information Typical applications include crawler cranes, mobile cranes, locomotive cranes, and DC-powered overhead travelling cranes. For rectifier-powered magnets, such as on AC cranes, select a Type M controller • Line-Arc ® Type M mill-type contactors • Reliable, simple circuitry, easy to maintain • Adjustable reverse current by rheostat inside the enclosure

Price
Electrical interlocks on lift contactor, single-pole double throw, with 1.1 A break rating on 230 VDC, wired to terminal block for customer’s use. Booster (over-excitation) relay provides a limited-time contact closure at the start of each lift, for connection to a customer’s generator shunt field circuit equipped for 275 V “pickup” and 190 V “carry,” in order to increase all-day lifting efficiency. A Class 6815 Lift-Drop master switch or pushbutton station (or equivalent 230 VDC rated pilot device) is required. Booster with 12 VDC pilot relays. Provides a contact closure same as R30 above, but includes Lift-Drop pilot relays designed for use with low-voltage 1-N.O. momentary-contact Lift-Drop pushbuttons and a separate control source from customer’s 12 V battery.

R34 †
Booster with 24 VDC pilot relays. Same circuit as R33, but designed for a 24 V battery.
† All booster (over-excitation) relay modifications require additional generator field circuitry and resistors properly matched to the generator. Square D is not in a position to specify or furnish this equipment. Therefore, controllers with booster relay modifications are recommended only to qualified crane manufacturers, or for replacement of existing booster-equipped controllers.
Pilot devices Use Lift-Drop pushbutton station or master switch.
